Simon views suicide as the result of many factors: diagnostic, epidemiological, genetic, familial, occupational, environmental, social, cultural, existential, and chance. Although he makes reference to all of these factors, primarily the first two, his focus is on behavior and symptoms in assessing suicide risk. He is concerned with “managing” risk, avoiding the use of the word “treatment.” Obviously, if you do not deal with risk, you will not have a patient to treat, but knowing and listening to patients as you do in psychotherapy has been an important source of our knowledge of suicide risk and the stimulus for research on this topic. Patients in treatment are an important part of the area of suicide research; not discussing them is a serious limitation of this otherwise fine book.
